BUG/MINOR: channel: initialize xfer_small/xfer_large on new buffers

These ones are only reset during transfers. There is a low but non-null
risk that a first full read causes the previous value to be reused and
immediately to immediately set the CF_STREAMER flag. The impact is only
to increase earlier than expected the SSL record size and to use splice().

This bug was already present in 1.4, so a backport is possible.
